- other
型別：Microsoft.SqlServer.Types.SqlGeography
A SqlGeography instance to compare against the instance on which STDisjoint is invoked.
傳回值
型別：System.Data.SqlTypes.SqlBoolean
A SqlBoolean value that indicates whether the SqlGeography instance is spatially disjointed from the specified SqlGeography. If the instances are spatially disjointed, this method returns true. Otherwise, false.
備註
Two geography instances are disjoint if the intersection of their point sets is empty.
This method always returns null if the spatial reference IDs (SRIDs) of the SqlGeography instances do not match.
